3 Claims.

This invention relates to paper containers such as are described in thespecification of Elmer Zebley Taylors application for United Statespatent Serial No. 570,427 filed 22nd. October 1931 5' and of Edmund PaulHerrmanns application for United States patent Serial No. 632,598 filedth. September 1932, in each of which a container is described comprisinga double-walled conical body in one end of which a bottom is secured.After filling a closure is applied to the other end, and thespecifications of such prior applications describe means forsubsequently opening the container consisting in different arrangementsof weakening lines or indentations around that end of the blank at whichthe container is to be opened, so that the portion between suchweakening lines or indentations can be readily torn out and entirelyremoved, exposing the contents for use as required.

The present invention is hereinafter shown and described as applied tocontainers constructed in accordance with the Herrmann applicationSerial No. 632,598 above referred to, in which the weakening lines arearranged parallel to each other and to the edge of the blank but arewider apart in the portion forming the outer ply than in that formingthe inner ply, and a cut is formed through the blank at the point wherethe wider and narrower spaced weakening lines or' indentations meet, sothat a tab is formed by pulling on which the portion between theweakening lines or indentationscan be torn out in a single turn aroundthe container.

The object of the present invention is however to provide a containerwhich while it can be opened by entirely removing the upper end thereofin the manner described in the prior applications above referred to, canif desired be only opened sufliciently to enable the contents to bepoured out, the partially torn out strip being then capable of beingreplaced and secured to protect the contents from the entrance of dust,flies, or other deleterious influences.

The invention is illustrated in the accompanying drawing, in which Fig.1 is a side elevation of part of a container constructed accordingthereto; Fig. 2 a view showing the container opened to enable thecontents to be poured out;

Fig. 3 a similar view showing the strip partly replaced to close thecontainer, and Fig. 4 a plan view of the blank for the body.

on reference to Fig. 4 it will be seen that the weakening lines orindentations 1, 2, formed in the body blank 3 arearranged parallel toeach other and to the edge of the blank at the end A of the latter whichforms the outer wall of the rolled-up container, and are then broughtcloser together at the points 4, 5, and subsequently continue parallelto each other and to the edge of the blank along the inner wall 13, acut 6 being made through the blank between the points 4 and 5 in such aposition that when the blank is rolled up it is as shown in Fig. 1slightly outside the outer edge of the outer wall and forms a tabwhichcan be grasped when it is desired to open the container. By pullingon this tab the entire strip 10 between the weakening lines 1, 2, can

be torn out by a single turn around the container, the inner narrow partof the strip being to facilitate this either partially or completely 7secured to the outer wider part, while the adhesion resulting from thetreatment with the paraffin wax or other material used for waterproofingor sterilizing the container will be sufiicient to hold the outer edgesof the wider part of the strip in contact with the outer surface of theinner wall of the container until the latter is opened in the mannerdescribed.

As thus far described the arrangement is similar to that covered in theprior application of Edmund Paul Herrmann hereinbefore referred to, butit will be clearly seen on reference to Fig. 4 that according to thepresent invention the weakening lines or indentations-1, 2, do notcontinue right up to the edge '7 of the part of the blank constitutingthe outer wall of the rolledup body, and that from the points 1 2*,where such weakening lines are stopped cuts 8, 9, are made through theblank, such cuts each extending inwardly from the point 1 or 2* acrossthe strip 10 between the weakening lines 1, 2, and then turningoutwardly and continuing to the extreme outer edge '7 of the blank.

The result of this arrangement is that when it is desired to open thecontainer by pulling on the strip 10 between the weakening lines 1, 2,:

after grasping the tab formed by the cut 6, as in the Herrmannapplication hereinbefore referred to, the flaps 11, 12, formed by thecuts 8, 9, will not be torn away, but will simply rise sufliciently toallow the strip 10 to pass them and will then return to their normalposition against the inner wall of the container. The mechanism forapplying the adhesive used in rolling up the body is so arranged thatsuch adhesive shall not be applied 'to the flaps 11, 12, so that thelatter will be free to rise as described.

The object of this arrangement is that if it should not be desired toentirely empty the container when first opened, the strip 10 may only betorn partly round as shown in Fig. 2, exposing an opening 14 between thelower surface of the closure 13 and the upper edge of the inner ply.ofthe body left by the removal of part of the narrower portion of thestrip. This opening is quite suflicient to enable the contents to bepoured out without the provision of a vent hole, and the extent to whichthe strip can be torn out may be previously determined if desired byarranging that the pasting mechanism employed shall definitely applyadhesive to cause the edges of the wider part of the strip 10 to beaflflxed to the inner layer of the body at a point such as 15 (Figs. 1and 4) which would stop the tearing at that point unless, if it isdesired to entirely remove the strip (as proposed in the Herrmannapplication above referred to) additional pressure is applied to carrythe tearing action beyond such point 15.

In any case if the strip 10 has not been completely removed the presentinvention enables the container to be closed again if all the contentshave not been poured out, as by slipping the free end of the strip underthe flaps 11, 12 (the commencement of this operation being illustratedin Fig. 3) the whole strip can be returned to practically its originalposition as shown in Fig. I

and will be held there by the engagement of such flaps with its upperand lower edges, thus closing the opening.

To facilitate thepouring out of the contents of a container opened inthe manner described, the sides of the torn portion of the strip 10 mayif desired be pinched together to form a spout or trough along which thecontents can pass.

Paper containers of the class to which the present invention is to beapplied are usually made and sold with the closure 13 at the smaller endin position, and after filling with the milk or other contents a closureof suitable type is to be inserted at the larger end, and the containeris preferably subsequently reversed so that the larger end becomes thebase. The form of the closures and the method of securing them inposition do not however form part of the present invention.

What I claim and desire to secure by patent is:-

1. A paper container comprising a doublewalled body and end closures andprovided with means for opening same, consisting of two rows ofweakening lines or indentations for the purpose of enabling the stripbetween them to be readily torn and turned back to leave an openingthrough the double walls thereof, and with means for sub sequentlyretaining the strip in its closing position comprising flaps adapted toengage its upper and lower edges and formed by cuts made in the outeredge of the outer wall and extending partially across the strip to thepoint where the weakening lines commence.

2. In a paper container comprising a doublewalled body and suitable endclosures, the formation of the body blank therefor with two weakeninglines spaced apart and so disposed that a wide strip can be torn out ofthe outer wall and a narrower strip out of the inner wall when it isdesired to open the container, and cuts being formed at the outer edgeof such blank to leave flaps which extend partly across the width of thestrip so that after the latter has been torn it can be replaced and willbe retained in its closing position by such flaps.

3. In a paper container comprising a doublewalled body and suitable endclosures, the formation of the body blank with two weakening lines whichare widely spaced in that part of the blank which constitutes the outerwall of the container and closer together in that part which constitutesthe inner wall, a out being made through the blank at the point wherethe wider and narrower weakening lines meet, the weakening lines beingstopped a short-distance from the outer edge of that part of the blankwhich forms the outer wall and cuts being formed leading from the pointsllii at which the weakening lines stop and extending inwardly partlyacross the strip and then turning 1 outwardly and continuing to the saidedge of the
